What is the MIS Package Substrate Fabrication Process?

The fabrication process of MIS (Mitsubishi Interconnect Substrate) Package Substrates typically involves several key steps to create a reliable and functional substrate for semiconductor packaging. Here’s an overview of the general fabrication process:

1. Substrate Material Selection: The process begins with selecting the appropriate ceramic material, such as alumina (Al2O3) or aluminum nitride (AlN), based on the application’s thermal, electrical, and mechanical requirements.
2. Substrate Preparation: The ceramic substrate material is prepared by cutting it into the desired size and shape, followed by surface preparation to ensure cleanliness and smoothness for subsequent processing steps.
3. Green Sheet Production (LTCC or HTCC): For LTCC (Low Temperature Co-Fired Ceramic) or HTCC (High Temperature Co-Fired Ceramic) substrates, ceramic powders are mixed with binders and solvents to form a slurry. This slurry is cast into thin sheets (green sheets) using a doctor blade or tape-casting process. Each green sheet contains circuit patterns, vias, and other features.
4. Layer Stacking and Lamination:Multiple green sheets, each with specific circuit patterns and vias, are stacked in the desired sequence to form a multilayer structure. The layers are aligned precisely to ensure accurate registration of vias and interconnections. The stacked green sheets are then laminated under controlled pressure and temperature to bond them into a monolithic structure.
5. Via Formation: After lamination, via holes are punched, drilled, or laser-ablated through the stacked layers where electrical connections (vias) are needed between different layers. These vias will later be filled with conductive materials to establish electrical continuity.
6. Metallization and Conductor Patterning: Conductive materials, such as thick-film pastes or thin-film deposition techniques (e.g., sputtering, evaporation), are used to deposit metal layers on the substrate surfaces. These metal layers form circuit traces, bonding pads, and other interconnect features according to the substrate design.
7. Firing (Sintering): The substrate undergoes a firing process in a controlled atmosphere kiln. During firing, the green sheets and deposited materials undergo chemical and physical transformations, resulting in densification and bonding of the ceramic layers. For HTCC, firing temperatures are higher to achieve denser and more robust substrates suitable for high-temperature applications.
8. Surface Finishing: After firing, the substrate surface may undergo additional processing steps such as polishing, planarization, or applying protective coatings to ensure smoothness, cleanliness, and protection against environmental factors.
9. Quality Control and Testing: Throughout the fabrication process, stringent quality control measures are implemented to verify dimensions, material properties, and electrical performance. Substrates are tested for reliability under various environmental conditions (temperature cycling, humidity, mechanical stress) to ensure they meet specified standards.
10. Assembly and Packaging: Once fabricated and tested, MIS Package Substrates are ready for assembly with semiconductor chips, passive components, and other electronic devices using appropriate bonding techniques (e.g., wire bonding, flip-chip bonding, soldering). This assembly process completes the integration of electronic components into the final electronic module or system.

By following these steps, manufacturers can produce MIS Package Substrates that offer high reliability, thermal performance, and electrical connectivity for a wide range of electronic applications, including automotive, telecommunications, and industrial equipment.

How do you manufacture a MIS Package Substrate?

Manufacturing a MIS (Mitsubishi Interconnect Substrate) Package Substrate involves a series of systematic processes designed to achieve precise dimensions, reliable electrical connections, and optimal thermal management. Here’s a detailed outline of the manufacturing process:

5. Via Formation: Punch, drill, or laser-ablate holes through the laminated stack where vias are required for electrical connections between layers.
6. Metallization and Conductor Patterning: Deposit conductive materials (e.g., thick-film pastes, thin-film deposition) onto the substrate surfaces to create circuit traces, bonding pads, and other interconnect features according to the substrate design.
7. Firing (Sintering):

   – LTCC: Fire the substrate in a controlled atmosphere kiln at lower temperatures (typically below 1000°C) to densify the ceramic layers and activate the conductive materials.

   – HTCC: Fire at higher temperatures (above 1000°C) to achieve denser ceramic layers suitable for high-temperature applications.

8. Surface Finishing: After firing, perform post-processing steps such as polishing, planarization, or applying protective coatings to enhance surface smoothness and protect against environmental factors.
9. Quality Control and Testing: Conduct rigorous quality checks throughout the manufacturing process to verify dimensional accuracy, material integrity, and electrical performance. Test substrates for reliability under various conditions (temperature cycling, humidity, mechanical stress).

6. Additional Features: Optional features such as special surface finishes, customized metallization schemes, or advanced testing and qualification procedures can add to the overall cost.
7. Supplier and Market Conditions: Pricing can also vary based on the supplier’s pricing strategy, market demand, and competitive landscape within the industry.

To provide a specific cost estimate, it would typically require a detailed assessment of the substrate’s specifications, volume requirements, and supplier quotations. Generally, MIS Package Substrates are considered a significant investment in electronic packaging due to their high performance, reliability, and specialized manufacturing processes.
